Geoinformatics Interview Questions and Answers
Question - 21 : - What Is Chart Junk?
Answer - 21 : -
chart junk : Unnecessary detail around maps and diagrams
Question - 22 : - Do You Know The Role Of Gps In Gis?
Answer - 22 : -
Competent decisions can only be rendered by reliable data and though GIS is an amazing data management tool, using it with GPS helps in validating the data analysis and results.
Question - 23 : - What Is Remote Sensing?
Answer - 23 : -
Remote sensing refers to detection and classification of objects on or in earth without physical contact, generally attained through aerial sensors.
Question - 24 : - What Are Gis Tools?
Answer - 24 : -
GIS tools on the other hand require interaction with the map canvas.
Question - 25 : - What Are Gis Commands?
Answer - 25 : -
Commands do not require interaction with the map, they just rely on surface.
Question - 26 : - What Is Geo-referencing?
Answer - 26 : -
Georeferencing is the process of associating plain digital images taken from a satellite or a plane with map coordinates so that they can be overlaid on street maps.
Question - 27 : - What Is Geo-coding?
Answer - 27 : -
Geocoding is when you associate a place name or an address with map coordinates.
Question - 28 : - Discuss Briefly Data “information” As One Component Of Gis
Answer - 28 : -
There are two basic types of map information in a GIS: Spatial and Aspatial (DESCRIPITIVE-attribute)
- Spatial refers to geographic features that are represented as raster (pixel) or vector (POINTS, LINES, and POLYGONS)
- Aspatial or Descriptive refers to TABULAR DATA which records characteristics of the geographic features
Question - 29 : - What Is The Difference Between Gis And Lis
Answer - 29 : -
Land Information System (LIS) is typical to GIS, but related primarily to large scale and parcel-based system such as Automated Mapping and Facilities Management (AM/FM)
Question - 30 : - What Is The Difference Between Automated Cartography, Cad, And Gis
Answer - 30 : -
GIS - Adds the analytical capabilities (graphic+ attribute) while automated cartography and CAD lack (graphic only)
